Q: Does this CyberPower UPS have a USB port?

A: Yes, this CyberPower UPS has a USB port.

Q: How many surge-protected outlets does this CyberPower UPS have?

A: This CyberPower UPS standby system has eight standard outlets.

Q: What is the joule rating of this CyberPower UPS?

A: This CyberPower UPS has an 890-joule rating.

Q: Is this CyberPower UPS ENERGY STAR certified?

A: Yes, this CyberPower UPS is ENERGY STAR certified.

Q: What is the maximum run time of this CyberPower UPS at full load?

A: The maximum run time at full load is 1.5 minutes.

Q: How long would this supply power to a typical Dell desktop and monitor? I believe the desktop has an SSD drive.

A: This type of backup is really only meant to cover quick power-outages and fluctuations. It weighs less than 4 pounds, so the battery is quite small. And it specifies it can handle full load for 90 seconds... and 6 minutes for half load. If would be safe to expect something in between those two numbers. There are too many variables in power consumption between different computers and monitors and actual usage to hazard a more accurate guess. As the manufacture states for this unit: "Battery backup keeps devices running during brief outages and provides enough run-time power for safe shut down." If you need more than that, then you'll need to look at stepping up from this unit. If you look at the specs for other units available at Best Buy, some will cover 2 hours of run time for a standard desktop and monitor... but those units are more expensive, bigger, and heavier, some over twenty pounds, because of the more substantial batteries. The APC Pro 1500VA is around 4x the price of this unit, but could allow you to work for 2 or more hours without interruption. If your down time costs you money, then think about investing in a more substantial unit.

Q: How long is the battery time if this was used to power a 12 watt LED lamp during a power outage Also how long will it store a full charge once unplugged

A: Hello DigDug, Thank you for your question. The CyberPower 450VA UPS will supply around 120 minutes for the 12 watt LED lamp. To store the UPS you will need to fully charge the unit overnight, and recharge the battery every three months to ensure optimal battery life.

Q: Does it have mounting holes on the back?

A: yes there are two mounting holes
